ことを特徴とするフイルム押圧装置。[Scope of Claim for Utility Model Registration] A film pressing device comprising a film pressing plate for pressing a film on a focusing plate disposed at a focal position of a lens system, comprising: a winding gear rotated by operation of a film winding lever; , an intermediate gear that rotates as the winding gear rotates to drive the film pressure plate; a winding gear that rotates as the winding gear rotates to drive the spool; and the intermediate gear. a first clutch mechanism that connects and disconnects the transmission of rotation from the film pressure plate to the drive mechanism of the film pressure plate; and a second clutch mechanism that connects and disconnects the transmission of rotation from the winding gear to the spool; , a first operation of setting the first clutch mechanism in an engaged state, setting the second clutch mechanism in a disengaged state, and releasing the film pressing state by separating the film pressure plate from the focusing plate; a second operation in which the mechanism is in the disengaged state, the second clutch mechanism is in the engaged state, and the film is wound while the film is released from the pressed state; A third operation of disengaging the clutch mechanism and pressing the film pressing plate against the reticle to set the film pressing state is performed in this order based on one film winding operation. A film pressing device characterized by:
